WASTE WOOD OF URBAN ORIGIN FOR ENERGY USE

The increasing demand for energy propels new areas of research in the search for sources that are economically viable and sustainable from an environmental point of view. In this sense, the objective of this study was to characterize a batch from urban wood waste aimed at energy use. We evaluate six different types of waste: solid wood, plywood, chipboard, MDF, OSB, and veneer. The residues were collected in a recycling plant in Piracicaba - SP and were taken to the laboratory to carry out the physical, chemical and thermogravimetric analyses. The experiment was conducted in a completely randomized design with three replicates per treatment (waste). Data analysis was performed by analysis of variance (ANOVA) and the Tukey test applied for multiple comparisons of means. Overall, there were no major differences between the results of solid wood residues and waste panels. Waste analyzed showed potential for energy use. It is recommended further studies to investigate the influence of different panels resins and coatings in its thermal degradation process.
